Abstract
Description
Technical Field
[0001] The invention relates to the technical field of concrete pouring, in particular to a large-volume concrete single-side formwork triangular support and an installation method thereof. Background Art
[0002] In modern construction, in most cases, buildings need to be constructed by building frame formwork and then pouring concrete. The frame formwork needs to be supported by external supports to prevent the frame formwork from shifting or collapsing due to internal pressure during the pouring process.
[0003] In general, during the pouring of concrete, equidistant supports are often used to support the pouring formwork, i.e., support structures with the same supporting force on the formwork.
[0004] In the pouring process of large-volume concrete, especially when only one-side formwork is used for support, the existing equidistant supports have the same supporting effect on each position of the formwork, but the pressures on different parts of the large-volume concrete are different, especially the middle part of the large-volume concrete is under greater pressure. Therefore, the existing equidistant supports are not suitable for pouring large-volume concrete and are prone to cause construction accidents.
[0005] To this end, the present invention provides a large-volume concrete single-side formwork triangular support and an installation method thereof. Summary of the invention
[0006] In order to make up for the shortcomings of the prior art, the problem that the above-mentioned ordinary equidistant supports are difficult to effectively support the large-volume concrete pouring process is solved.
[0007] The present invention provides a triangular support for a single-sided formwork of a large volume of concrete, comprising: a formwork, a triangular support is arranged on one side of the formwork, the triangular support is a right triangle as a whole, the upper end of the triangular support is a relatively small acute angle, the side not close to the formwork is connected to the foundation part through a bolt rod, an anchor bolt is arranged on the side of the triangular support close to the formwork, and the anchor bolt is pre-buried in the foundation, and only the threaded part extends out of the foundation, the outer side of the anchor bolt is threadedly connected to a connecting nut, one side of the connecting nut is threadedly connected to an outer connecting rod, the outer connecting rod has the same thread as the anchor bolt, and the outer connecting rod and the anchor bolt are fixed by the connecting nut The outer side of the outer connecting rod is slidably connected with a steel pad, which is used to tighten the outer connecting rod. The formwork and the triangular support are fixedly connected by a connecting piece. Multiple connecting pieces are installed on one triangular support, and are assembled and installed by threaded rods and gaskets. An adjusting piece is fixedly connected to the upper side of the triangular support. The adjusting piece extends from the upper end of the triangular support toward the side away from the formwork, and is used to adjust the verticality of the formwork. The above-mentioned connections can make the formwork firm and reliable, ensure the verticality and flatness of the concrete, and utilize the stability of the triangle to effectively block the side pressure of the concrete and ensure the safety of the formwork support.
[0008] Furthermore, a co-vibration structure is provided on the upper side of the template, and a scraping structure is provided in the co-vibration structure. The co-vibration structure includes meshing teeth provided on one side of the template, and the meshing teeth are away from the casting side. Clamping grooves are provided on both sides of the template for clamping between the templates. Except for the middle template, the templates on both sides are installed with clamping blocks that can be used in conjunction with the clamping grooves, so that the templates can be spliced, and the templates at both ends are in a state of having a clamping block at one end and a clamping groove at the other end, which is convenient for subsequent expansion and installation of the templates, and side plates can be installed at the two ends of the spliced templates to limit the casting area, and one side of the meshing tooth is meshed with a transmission gear, and the transmission gear remains meshed with the meshing tooth.
[0009] Furthermore, a reciprocating motor is fixedly connected to one side of the transmission gear, and the reciprocating motor can set its own rotation cycle according to the actual length of the template to ensure that the moving block can make a complete reciprocating motion along the spliced template, which is used to drive the transmission gear to rotate, and can set its own operation cycle according to the total length of the template. A moving block is slidably connected to the upper side of the template, and the reciprocating motor is fixedly connected to the moving block. A slot is provided in the moving block for installing the reciprocating motor.
[0010] Furthermore, a bearing sleeve is fixedly connected to one side of the moving block. The moving block is concave as a whole and fits the upper side of the template. The bearing sleeve is used to load a vibration rod for exhausting the poured concrete. The vibration rod is composed of a vibration motor and a rod member for transmitting vibration. The vibration of a fixed frequency emitted by the vibration motor can be transmitted to the poured concrete through the rod member, thereby causing resonance and movement inside the poured concrete, thereby reducing the gap in the poured concrete and expelling bubbles. The exhaust action is always performed during the pouring process, which can solve the problem of difficult manual operation. In addition, the exhaust operation can be performed throughout the entire process of pouring concrete, so that all positions of the poured concrete are subject to the exhaust operation, further avoiding the problem of missing exhaust positions due to manual operation errors, and improving the quality of poured concrete.
[0011] Furthermore, the scraping structure includes through holes, which are opened on the moving block. The through holes are two square holes of uniform size and symmetrical distribution. A straight rod is slidably connected to the moving block, and the straight rod passes through the through holes. The two straight rods are the same in size and shape.
[0012] Furthermore, both ends of the straight rod are fixedly connected with round sleeves, and the inner side of the round sleeve is rotatably connected with a connecting round rod. The connecting round rod consists of two parts, one part is the round rod part, which is rotatably connected in the round sleeve, and the other part is the plate part, which is used to connect the round rod part and the scraper plate.
[0013] Furthermore, a scraper plate is fixedly connected to one side of the connecting round rod, and the scraper plate can scrape the poured concrete splashed to the upper end of the formwork during the pouring process. A clamping block is fixedly connected to the straight rod, and the clamping block is only located on the straight rod close to the pouring side. The clamping blocks are respectively located on both sides of the moving block, and the clamping blocks are only located on the straight rod close to the pouring side. The clamping block is used to fix the angle of the scraper plate when it moves. A resistance increasing plate is fixedly connected to the bottom side of the scraper plate, and the scraper plate and the resistance increasing plate both fit the upper surface of the formwork. The friction between the resistance increasing plate and the formwork is greater than the friction between the scraper plate and the formwork. By changing the scraping angle during the reciprocating motion, the scraper plate can sweep most of the splashed poured concrete back into the pouring area during the reciprocating motion, thereby not only ensuring that the movement of the moving block is not blocked, but also reducing the material waste of pouring concrete.
[0014] A method for installing a large-volume concrete single-side formwork triangular support according to the above method comprises the following steps: Furthermore, the buried parts are partially installed. After the concrete needs to be poured, the anchor bolts are pre-buried into the foundation at a reasonable interval, and the anchor bolts and the additional steel bars of the main reinforcement of the structure are spot welded; Furthermore, the formwork and the single-sided bracket are installed. The formwork is set up according to the scope of pouring concrete. The formwork is in an upright state, and the triangular support is hoisted to the rear side of the formwork. The anchor bolts and the outer connecting rod are connected with connecting nuts, and the outer connecting rod is fastened with a steel pad at the rear end of the outer connecting rod. Finally, the formwork and the triangular support are connected through adjusting parts.
[0015] The beneficial effects of the present invention are: The large-volume concrete single-sided formwork triangular support described in the present invention can make the formwork firm and reliable, ensure the verticality and flatness of the concrete, and utilize the stability of the triangle to effectively block the side pressure of the concrete, thereby ensuring the safety of the formwork support, by connecting the formwork and the triangular support as well as the anchor bolts, external connecting rods, connecting nuts and other structures therein in sequence.
[0016] The large-volume concrete single-sided formwork triangular support described in the present invention drives the vibrating rod thereon to move back and forth along the reciprocating screw rod through the moving block, so that the exhaust action is always performed during the pouring process, which can solve the problem of difficult manual operation. In addition, the exhaust operation can be performed during the whole process of concrete pouring, so that all positions of concrete pouring are subject to the exhaust operation, further avoiding the problem of missing the exhaust position caused by manual operation errors, and improving the quality of concrete pouring.
[0017] The large-volume concrete single-side formwork triangular support described in the present invention changes the scraping angle of the scraping plate through the scraping plate and the resistance-increasing plate installed thereon, so that the optimal angle can be maintained to clean the splashed poured concrete and most of the poured concrete can be swept back to the pouring area, thereby not only ensuring that the movement of the moving block is not blocked, but also reducing the material waste of pouring concrete.

[0021] Embodiment 1 like Figures 1 to 7 As shown, a large volume concrete single-side formwork triangular support according to an embodiment of the present invention, please refer to Figure 1 , Figure 2, Figure 3 , including: a template 1, a triangular support 2 is arranged on one side of the template 1, the triangular support 2 is a right triangle as a whole, the upper end of which is a small acute angle, and the side not close to the template 1 is connected to the foundation part through a bolt rod, and the side of the triangular support 2 close to the template 1 is provided with an anchor bolt 21, and the anchor bolt 21 is pre-buried in the foundation, and only the threaded part extends out of the foundation, the outer side of the anchor bolt 21 is threadedly connected to a connecting nut 22, and one side of the connecting nut 22 is threadedly connected to an outer connecting rod 23, and the outer connecting rod 23 has the same thread as the anchor bolt 21 The outer connecting rod 23 and the anchor bolt 21 are fixed by connecting nuts 22. The outer side of the outer connecting rod 23 is slidably connected with a steel washer 24, and the steel washer 24 is used to fasten the outer connecting rod 23. The template 1 and the triangular support 2 are fixedly connected by a connecting piece 25. A plurality of connecting pieces 25 are installed on one triangular support 2, and are assembled and installed by means of threaded rods and gaskets. An adjusting piece 26 is fixedly connected to the upper side of the triangular support 2. The adjusting piece 26 extends from the upper end of the triangular support 2 toward the side away from the template 1, and is used to adjust the verticality of the template 1.
[0022] Specifically, after selecting the position where concrete needs to be poured, the anchor bolts 21 are first embedded in the foundation, and the anchor bolts 21 and the additional steel bars of the main reinforcement part of the structure are spot welded. Then, the formwork 1 is set up according to the range of concrete pouring. The formwork 1 needs to be erected and located at the position where it needs to be installed. Then, the triangular support 2 is hoisted to the rear side of the formwork 1 and installed with the embedded anchor bolts 21. Then, the anchor bolts 21 and the outer connecting rod 23 are connected with the connecting nut 22, and the outer connecting rod 23 is fastened with a steel pad 24 at the rear end of the outer connecting rod 23. The formwork 1 is spliced in sequence until the formwork 1 and the wall form the required pouring area. Finally, the formwork 1 and the triangular support 2 are connected by the adjusting member 26. The above-mentioned sequential connection can make the formwork 1 firm and reliable, ensure the verticality and flatness of the concrete, and utilize the stability of the triangle to effectively block the side pressure of the concrete, thereby ensuring the safety of the support of the formwork 1.
[0023] Embodiment 2 Please refer to Figure 4 , Figure 5, compared with Example 1, another embodiment of the present invention is: a vibration-coordinating structure 3 is provided on the upper side of the template 1, and a scraping structure 4 is provided in the vibration-coordinating structure 3, the vibration-coordinating structure 3 includes a meshing tooth 31 provided on one side of the template 1, and the meshing tooth 31 is far away from the casting side, and clamping grooves 32 are provided on both sides of the template 1 for clamping between the templates 1, except for the middle template 1, the templates 1 on both sides are installed with clamping blocks that can be used in conjunction with the clamping grooves 32, so that the templates 1 can be spliced, and the templates 1 at both ends are in a state of having a clamping block at one end and a clamping groove 32 at the other end, which is convenient for the subsequent expansion and installation of the template 1, and the upper side plates can be installed at the two ends of the spliced template 1 to limit the casting area, and a transmission gear 33 is meshed on one side of the meshing tooth 31, and the transmission gear 33 is kept meshing with the meshing tooth 31.
[0024] Please refer to Figure 4 A reciprocating motor 34 is fixedly connected to one side of the transmission gear 33. The reciprocating motor 34 can set its own rotation cycle according to the actual length of the template 1 to ensure that the moving block 35 can make a complete reciprocating motion along the spliced template 1, which is used to drive the transmission gear 33 to rotate, and can set its own operation cycle according to the total length of the template 1. A moving block 35 is slidably connected to the upper side of the template 1, and the reciprocating motor 34 is fixedly connected to the moving block 35. A slot is provided in the moving block 35 for installing the reciprocating motor 34.
[0025] Please refer to Figure 1 , Figure 4 and Figure 5 A bearing sleeve 36 is fixedly connected to one side of the moving block 35. The moving block 35 is concave as a whole and fits the upper side of the template 1. The bearing sleeve 36 is used to load a vibration rod for exhausting the poured concrete. The vibration rod is composed of a vibration motor and a rod for transmitting vibration. The vibration of a fixed frequency emitted by the vibration motor can be transmitted to the poured concrete through the rod, so that resonance is generated inside the poured concrete and it moves, so that the gap in the poured concrete becomes smaller, thereby exhausting bubbles.
[0026] Specifically, when the formwork 1 is installed and calibrated through the triangular support 2, the pouring area can be poured. During the pouring process, it is necessary to use a vibration rod to exhaust the poured concrete. After the vibration rod is loaded in the bearing sleeve 36, the reciprocating motor 34 can be started. When the reciprocating motor 34 is started, it can drive the transmission gear 33 to rotate. Since the transmission gear 33 and the meshing tooth 31 are meshed, the transmission gear 33 can move along the square of the meshing tooth 31, thereby driving the moving block 35 to move along the formwork 1, and the movement direction can also be changed according to the change of the rotation direction of the reciprocating motor 34, thereby driving the vibration rod installed in the bearing sleeve 36 on the moving block 35 to vibrate and exhaust the poured concrete. The exhaust action is always performed during the pouring process, which can solve the problem of difficult manual operation. In addition, the exhaust operation can be performed throughout the entire process of pouring concrete, so that all positions of pouring concrete are subjected to the exhaust operation, further avoiding the problem of missing exhaust positions caused by manual operation errors, thereby improving the quality of poured concrete.
[0027] Please refer to Figure 6 , Figure 7 , compared with Example 2, another implementation of the present invention is: the scraping structure 4 includes a through hole 41, the through hole 41 is opened on the moving block 35, the through hole 41 is two square holes of uniform size and symmetrical distribution, the moving block 35 is slidably connected with a straight rod 42, and the straight rod 42 passes through the through hole 41, and the two straight rods 42 are the same in size and shape.
[0028] Please refer to Figure 6 , Figure 7 The two ends of the straight rod 42 are fixedly connected with a circular sleeve 43, and the inner side of the circular sleeve 43 is rotatably connected with a connecting circular rod 44. The connecting circular rod 44 consists of two parts, one part is a circular rod part, which is rotatably connected in the circular sleeve 43, and the other part is a plate part, which is used to connect the circular rod part and the scraping plate 45.
[0029] Please refer to Figure 7 A scraper plate 45 is fixedly connected to one side of the connecting round rod 44, and the scraper plate 45 can scrape the poured concrete splashed to the upper end of the template 1 during the pouring process. A clamping block 46 is fixedly connected to the straight rod 42, and the clamping block 46 is only located on the straight rod 42 close to the pouring side. The clamping blocks 46 are respectively located on both sides of the moving block 35, and the clamping blocks 46 are only located on the straight rod 42 close to the pouring side. The clamping block 46 is used to fix the angle of the scraper plate 45 when it moves. A resistance increasing sheet 47 is fixedly connected to the bottom side of the scraper plate 45. The scraper plate 45 and the resistance increasing sheet 47 both fit the upper surface of the template 1, and the friction between the resistance increasing sheet 47 and the template 1 is greater than the friction between the scraper plate 45 and the template 1.
[0030] Specifically, when the moving block 35 moves, it will carry the scraper plate 45 thereon with it. Because there is a resistance increasing plate 47 at the position where the bottom side of the scraper plate 45 contacts the upper side of the template 1, and the friction between the resistance increasing plate 47 and the template 1 is relatively large, the part with the resistance increasing plate 47 will lag behind in movement due to the large friction during the movement of the scraper plate 45, thereby driving the scraper plate 45 to be inclined. The straight rod 42 is provided with a card block 46, which can limit the movement limit of the straight rod 42, so that the scraper plate 45 is kept moving at a certain angle during the movement of the moving block 35. At this angle, the scraper plate 45 can scrape the poured concrete on the template 1, and by changing the scraping angle during the reciprocating motion, the scraper plate 45 can sweep most of the splashed poured concrete back into the pouring area during the reciprocating motion, thereby not only ensuring that the movement of the moving block 35 is not blocked, but also reducing the waste of poured concrete materials.
[0031] A method for installing a large-volume concrete single-side formwork triangular support according to the above method comprises the following steps: The embedded parts are installed. After the concrete is poured, the anchor bolts 21 are embedded in the foundation at a reasonable interval. The anchor bolts 21 and the additional steel bars of the main reinforcement of the structure are spot welded. The formwork and the single-sided bracket are installed. The formwork 1 is set up according to the scope of pouring concrete. The formwork 1 is in an upright state, and the triangular support 2 is hoisted to the rear side of the formwork 1. The anchor bolts 21 and the outer connecting rod 23 are connected with the connecting nuts 22, and the outer connecting rod 23 is fastened with a steel pad 24 at the rear end of the outer connecting rod 23. The formwork 1 is spliced in sequence until the formwork 1 and the wall form the required pouring area. Finally, the formwork 1 and the triangular support 2 are connected by the adjusting piece 26.
[0032] How it works After selecting the location where concrete needs to be poured, the anchor bolts 21 are embedded in the foundation first, and the anchor bolts 21 and the additional steel bars of the main reinforcement of the structure are spot welded. Then, the template 1 is set up according to the range of concrete pouring. The template 1 needs to be erected and located at the location where it needs to be installed. Then, the triangular support 2 is hoisted to the rear side of the template 1 and installed with the embedded anchor bolts 21. Then, the anchor bolts 21 and the outer connecting rod 23 are connected with the connecting nut 22, and the outer connecting rod 23 is fastened with a steel pad 24 at the rear end of the outer connecting rod 23, and the templates are spliced in sequence. The template 1 and the wall form the required pouring area, and finally the template 1 and the triangular support 2 are connected by the adjusting member 26. When the template 1 is installed through the triangular support 2 and the calibration is completed, the pouring area can be poured. During the pouring process, the pouring concrete needs to be exhausted by a vibration rod. After the vibration rod is loaded in the bearing sleeve 36, the reciprocating motor 34 can be started. When the reciprocating motor 34 is started, the transmission gear 33 can be driven to rotate. Since the transmission gear 33 is meshed with the meshing tooth 31, the transmission gear 33 can be moved along the meshing tooth 31. The square movement of the meshing teeth 31 drives the moving block 35 to move along the template 1, and the movement direction can be changed according to the change of the rotation direction of the reciprocating motor 34, thereby driving the vibration rod installed in the bearing sleeve 36 on the moving block 35 to vibrate and exhaust the poured concrete. When the moving block 35 moves, it will carry the scraper plate 45 on it to move. Because there is a resistance increasing piece 47 at the position where the bottom side of the scraper plate 45 contacts the upper side of the template 1, and the friction between the resistance increasing piece 47 and the template 1 is relatively large, during the movement of the scraper plate 45 The part with the resistance increasing plate 47 will lag in movement due to the large friction, thus driving the scraper plate 45 to be inclined, and the straight rod 42 is provided with a block 46 to limit the movement limit of the straight rod 42, thereby keeping the scraper plate 45 moving at a certain angle during the movement of the moving block 35. At this angle, the scraper plate 45 can scrape the poured concrete on the template 1, and by changing the scraping angle during the reciprocating motion, the scraper plate 45 can sweep most of the splashed poured concrete back into the pouring area during the reciprocating motion.
[0033] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
